Title: Improvements in or relating to automatic fire-arms
IPC: F41A23/20
Filed: 1921-03-11
Abstract: 167,727. Pirmez, H. March 11, 1921. Disappearing-gun mounts; housing.- Relates to a mounting for a distantlycontrolled machine gun with a self-acting sweeping traverse as described in Specification 147,673 in which the gun 1 is mounted in a vertical position on a piston 16 so as to be concealed within a cylinder 20, which is buried in the ground. On releasing a catch 26 by an electro-magnet 33 controlled from a distant observation post, the gun is projected upwards by a spring 25 and automatically swings to the horizontal firing position. According to the present invention, the gun swings on trunnions 5 on a base-plate 3 pivoted to the upper end of a vertical spindle 15 which receives an alternating traversing movement. This movement is effected by means of linkage 54, 53, Fig. 3, adjustably connected to a crank 51, which is continuously rotated through spur-gear 48, 49 by a centrally-arranged clock spring 44. On closing a distant switch by hand or by means of Hertzian waves, a ring 30 which retains the pivoted catch 26 is raised and the piston rises on guides 21 by the expansion of the spring 25 until it is brought to rest by buffers 36 whereupon catches 37 engage the top of the cylinder to prevent downward movement. The gun is meanwhile automatically moved to the horizontal position by a spring 38 and retained by catches 40, 39, firing being started by the engagement of a trigger or sear member 41 with a fixed button 42. The clockspring 44 being wound and held by a pawl 47 starts the traverse as soon as the crank 51 is free from the cylinder. An adjustable coupling 55 in the spindle 15 or a turn-buckle in the link 53 enable the centre of traverse to be initially adjusted and a turn-buckle 10 enables the elevation of the gun for range to be adjusted.

Title: Improvements in or relating to the preparation of permonosulphates
Inventor: HILDON ANTHONY MACDONALD
IPC: C01B15/08
Filed: 1958-03-11
Abstract: Permonosulphates of Na, K, Li, Cs, Ca, Sr, Ba, Mg, Zn, and ammonium are prepared by direct reaction between the appropriate pyrosulphate and hydrogen peroxide which is preferably employed in a concentration of at least 80% w/w based on the total water + hydrogen peroxide content of the reactant.  The minimum concentration of hydrogen peroxide is such as would produce a final product containing at least 0.5% of available oxygen.  The oxidation of the pyrosulphate is preferably effected with a limited amount of water.  According to examples: (2) potassium pyrosulphate, prepared by reacting potassium sulphate with sulphur triooxide and containing about 6% of free sulphur trioxide, was mixed with 97% hydrogen peroxide to form a paste of potassium permonosulphate.  Sodium and magnesium permonosulphate may be similarly prepared.  (5) zinc pyrosulphate was prepared by reacting zinc sulphate and sulphur trioxide and this was mixed with 99% hydrogen peroxide to form a paste which converted to zinc permonosulphate.

Title: Improvements in or relating to the separation of dissolved solids by evaporation
IPC: B01D1/00
Filed: 1933-03-15
Abstract: <PICT:0411624/III/1> In crystallizing solutions by cooling or evaporation, contamination of the precipitate by impurities is prevented by transferring the precipitate as it forms from the evaporating zone to a zone isolated therefrom but in circulatory communication therewith and passing the incoming solution on its way to the evaporating zone through the precipitate.  Spent oxide from gas works is charged into a series of extractors 1, 2, 3, through which solvent, e.g. carbon disulphide, is fed in counterflow.  The solution, after passage through filters 5, 6, gravitates to pump tanks 19, 20 from which it is forced to the crystallization plant. The latter comprises a vertical evaporator 21 having a conical bottom 22 connected to two precipitate receivers 26, 27 by valved pipes 34, 35.  The solution is pumped through pipes 28, 29, 30 into the bottom of one or other of the receivers 26, 27 and flows upwardly through the receivers and thence into the evaporator from which it is returned through the pipes 35.  The receivers are provided with stirrers, perforated plates 33 for supporting the crystals, and jackets 37 for cooling medium.  The process may be applied to the separation of pure sodium chloride from solutions containing sodium hydrate produced by the electrolysis of sodium chloride and also the separation of sodium chloride from solutions containing sodium chloride and glycerol.

Title: Sealing arrangement between two relatively moving components
IPC: F16J15/44
Filed: 1966-02-23
Abstract: 1,093,530. Seals. BETEILIGUNGSUND PATENTVERWALTUNGS G.m.b.H. Feb. 23, 1966 [Feb. 24, 1965], No. 7967/66. Heading F2B. [Also in Division F1] A sealing arrangement between two relatively moving components and between two pressure chambers at different pressures to seal the chamber at the lower pressure from the chamber at the higher pressure, comprises, in its simplest form, a sealing strip 6, Fig. 3, loosely mounted in a recess 4 in one component 2 moving relatively to a second component 1. Initially the strip 6 lies parallel to the component 1 leaving a gap 3 therebetween through which a pressure drop occurs with the pressure dropping linearly towards the lower pressure chamber. At the same time the pressure in the higher pressure chamber is translated to the recess 4 behind the strip 6 and is unable to leave the recess since the strip is urgent to narrow the clearance between it and the low pressure end of the recess 4. The substantially constant pressure on the rear face of the strip acts in opposition to the pressure drop occurring on the front face of the strip to cause tilting of the strip and sealing engagement of the strip with the component 1 at that end adjacent the lower pressure chamber. The strip instead of being rectangular in crosssection may be trapezoidal and have a face adjacent the component 1 which slope towards the component 1 at the lower pressure chamber end of the strip. Alternatively the recess 4 may be obliquely positioned in the component 2 to give the same effect. In another embodiment, the strip may consist of a flexible tongue 9, Fig. 16, formed integral with a holding member 10 secured to the component 2 by a bolt 11. A hole 12 permits ingress of pressure into the recess 4 and a sealing cord 15 prevents egress therefrom. Two such tongues 9 may project in opposite directions from the holding member 10, with one tongue being operative when the pressure drop is in one direction and the other tongue operative when the pressure drop is in the other direction. Alternatively, there may be two holding members having a tongue on each, extending towards each other. The recess 4 is then divided into two by a web extending outwardly from the base of the recess. In a further embodiment, a projection on the rear face of a rectangular strip sealingly engages a groove in the bottom of the recess to divide the recess equally into two parts. The narrow sides of the strip are sealed against the sides of the recess and passages which cross each other connect the halves of the recesses to the gap 3.

Abstract: 1,058,964. Forming curved pipes. G. MARCHIOLI. Feb. 26, 1965 [Feb. 26, 1964; Jan. 19, 1965], No.8503/65. Heading B5A. Curved pipes are formed by pressing a fibrous slurry, of, e.g., asbestos-cement, between a curved expansible core and an outer mould, the core being withdrawn from the moulded pipe by rotating the core relative to the pipe about an axis at the centre of curvature of the pipe. In one embodiment (see Figs. 1-4, only Fig. 3 shown) the pipe is formed between fixed and reciprocable permeable mould halves (4) and (17) respectively, and a hollow core (20) covered by an expansible membrane 23 and pivoted by bell-crank 25 about an axis 26 which lies at the centre of curvature of the mould cavity and the core. In operation the ends of the mould cavity are closed by forwarding piston-operated end-plates 30 and 31, which carry socket forming member 27 and straight end forming member 28 respectively. The slurry is then injected into the cavity, and the membrane 23 internally expanded by fluid pressure. The plates 30, 31 are subsequently withdrawn, the upper mould half raised and the core pivoted about axis to withdraw it from the pipe which is retained by the lower mould half. In a second embodiment (see Figs. 5-11, not shown) the core is vertically, reciprocable by means of piston-andcylinder means (132), attached thereto through collar (123a) and rod (123), so that upon withdrawal of the upper mould half the core with the finished tube may be raised clear of the lower mould half whilst the core and pipe are rotated relatively to facilitate withdrawal of the core.
